: BOGIE FOB, RAILWAY CARS AND THE LIKE.

Application filed July 13, 1926, Serial No. 122,217, and in SWeden JuIy 16, 1925.

In a co-pending patent applicationSerial No. 8190 1, filed June 18, 1926, by Lars G. H. l-lelmstein, certain improvements in bogies for railway cars and the like are described and illustrated, in which the'beam is provided with vertically extending, throughgoing holes into which supporting springs for the bogie can be introduced from below. These holes are suitably fitted, at the lower part of the beam, with shoulders or the like extending along a portion of the circumference of the hole and forming support for a spring-carrying washer. The spring is, suitably, located between two washers having central through-going holes, the lower washer being provided at its edge with recesses corresponding to shoulders in the hole of the beam so as to allow the spring to be compressed by means of a bolt and tobe inthe washers. The lower washer is provided at its edge with downward projections adapted to be engaged by the shoulders in the hole of the beam so as to efiectively prevent the washer from turning. 1

The object of this invention is tofurther improve the said bogie suspension device, particularly with a view of providing a larger supporting area for the lower washer. The invention consists, chiefly, in the I 1 downward projections at the edge of the lower washer fitting into recesses in the shoulders in the hole of the beam.

In the drawing, an embodiment of the improved bogie supporting device is illustrated by way of example. Fig. 1 is a section of the beam through the hole receiving the spring. Fig. 2 is a side elevation of the beam with the spring bracket. Fig. 3 is a plan view'of the beam at the hole. Figs. 4: and 5 are side elevation and plan views, respectively, of the lower washer.

ser-ted and removed as a unit together with Referring to the drawing, the beam 3 by means of a spring 4 carries the bogie frame o. The spring l is located in a cylindrical through-going hole 6 of the beam 3 and bears with its ends on a lower washer 7 and an upper washer 8, said latter washer bearing on a bracket fastened to the bogie frame. The washer 7 is provided at its edge with recesses 9 corresponding to shoulders 10 in the hole of the beam, thus forming a bayonet-lock for the washer 7. This washer 7 is provided, according to the invention, with downward projections 11 (Fig. .l) fitting in recesses 18 in the supporting shoulders 10 in the hole of the beam. By this arrangement the advantage is gained that the projectionsll do not require any extra space, consequently, the supporting shoulders 10 can be made longer so as to present a larger supporting area for the lower washer.

We claim In a bogie supporting device, the combi- 6 nation of beams having vertically extending, I through-going holes, supporting springs for the bogie placed in the said holes, shoulders provided at the lower part of the said holes,

said shoulders extending along a portion of 7 the circumference of the holes, washers carried by the said shoulders and serving to support the said springs, and projections extending from the edges of the said washers and fitting in recesses in the shoulders in the hole of thevbeam,substantiallyas and for the purpose set forth.

In testimony whereof we have signed our names.
